Specification of Letters Patent,

Patented Sept. 7, 1909.

Application filed October 30, 1908. Serial No. 460,235.

To all whom it may concern:

lie itknownthatl, (inouon li. Anemia, a citizen ot the United States,residlng at Leominster, in the county of \Vorcester and an improvedfilling detector mechanism of simple construction, and having a fillingfeeler or detector, preferably located on the magazine end of the loom,and which is the direction of arrow a, same figure. Fig.-

adapted to mentor, preferably through an opening in the rear wall of thestationary shuttle box at said end, and through an opening in the rearwall of the shuttle,.to engage the filling on the bobbin, at every otherforward movement of the lay, when the active shuttle enters thestationary shuttle box at themagazine end ofthe lay, and on thepractical or substantial exhaustion of filling in said shuttle to utinto operation mechanism to cause the operation of the weft replenishingmechanism, to supply fresh filling on the same pick, and without theshuttle going over to the other end of the loom, and returning to themagazine end.

My invention consists in certain novel features of construction .of myimprovements which are adapted to be applied to andzused on any ordinaryweft replenishing loom.

I have shown in the drawings a detached portion of the magazinecndof aloom, and a stationary shuttle box, and a magazine of the rotary typefor filling carriers, with my improvements combined therewith.

Referring to the drawings :Figure 1 is a sectional end View of themagazine end of the lay, and of my improvements in filling detectormechanism, showing the lower portion of a rotary magazine. Fig. 2 is arear view ofthe lay shown in Fig. 1, looking in 3 is a plan view of aportion of the magazine end of the lay, and ofthe shuttle box,

' looking in the direction of arrow 12, Fig. 1.

Some parts are shown in section, and some parts are broken away. Flg. 4corresponds to Fig. 3, but shows some: ofthe parts in ditt'ereutpositions.

In the accompanying drawings, '1 is a portion of a lay beam carried onthe lay sword 2; 3 is a detached portion of a stationary shuttle box atthe magazine end of the loom,

and 4 a shuttle therein, carrying-a bobbin 5 having filling 6 thereonw 7is the lower detached portion of a stationary magazine of the ordinarytype, which is mounted to rotate on a stand 8, secured at the front ofthe loom side, not shown, in the usual way.

9 is the transferrer arm, which is pivotallymounted on a stud 10, andhas a downwardly extending arm 9.

All'of the above" mentioned parts may beof any usual and well knownconstruction.

I will now describe my improvements. The back wall of the stationaryshuttle box .3 has in this instance two bosses 3, see Fig. 1, for-averticallyjextending stud 11.

On the stud 11 is loosely mounted the hub 12' of the filling feeler 12.The filling feeler 12 is inthis instance of frame-like construction, asshown, and has a pivotal motion toward and away from the shuttle; saidfeeler 12 has in this instance a flattened end 12 which is adapted toenter through an opening in the back wall of the shuttle box 3, andthrough an opening in the rear of the shuttle 4, to feel against thefilling 6 on the bobbin), see Figs. 3, and 4. A rear-wardly extending.part 12' on the feeler 12, has pivotallyconnected thereto the rod-head13 on a rod or connector 13. The opposite end of said connector 13has'the rod-head 13 thereon, which is pivotally connected to the upperend of a lever 14, see Fig. 2. The

lever 14 has its hub 14" loosely mounted on a stud 15 on a projection 16on the hub 16 of a lever 16, see Fig. 1. The hub 16 of the lever 16 isloosely mounted on a stud 17 on the rear of the lay beam. Extending outfrom the hub 14 of the lever 14 is a side" projection or foot 14" whichextends in the path of and is adapted to he engaged by the upper edge ofthe" lever 16, see Fig. 2. A

yielding connection between the lever 16 and: v

. 24, which in this instance has at its outer end 'ing, see Fig. 4, withthe headed end 20 of a of hardened steel. The plate 24 extends ininstance has a hub 26 secured on the lower shaft 27 is mounted inbearings 28 on the the extension 14" on the lever 14, so that 1 on thedownward movement of the lever 16, the spring 18 will expand and leavethe lever 14 practically stationary without moving the connector 13 andthe filling detector 12, in case the amount of filling 6 on the bobbin 5prevents the filling detector 12 from moving into the shuttle, as shownin Fig. 3. The upward movement of the lever 16, through the engagementof its upper edge with the projection or foot 14 on the lever-.14, willpositively move said lever 14, and through the connector 13, move thefeele'r 12 out of the shuttle and out of engagement with the filling, asshown by broken lines in Fig. 4. A downwardly extending rod or connector19 is attached to the lever 16, and is connected at its lower end withsuitable cam 1 operating mechanism, not shown, to operate the lever 16and the lever 14, and through intermediate connections to the feeler 12,to operate said feeler, as above described, to en-' gage with, thefilling on the bobbin in the shuttle every other pick, in the usual way.

The feeler or detector 12 has in this instance thereon a projection 12,having a curved or cam-shaped end, which is adapted to engage, on thepractical exhaustion of fillscrew 20, which is adjust-ably secured inthe end of an arm or lever 21. The lever 21 in this'instance has its hub21 secured by a set screw 22 on the upper end of a vertically extendingshaft 23, which has bearings in the lay beam 1.' ()n the lower end ofthe shaft 23 is secured the hub 24 of an arm or lever a plate 24",preferably detachable, and made the path of and is adapted to engage theend of a hardened steel plate 25, which is preferably detachably securedon the inner end of a lever 26, see Fig: 3, which lever in this end of avertically extending shaft 27. The

front of the lay beam 1, and on the upper end of the shaft 27 is securedin this instance the hub 29 of a bunter 29, which extends upwardly andwith its upper end in the path of and adapted'to engage, in thisinstance, the rounded grooved end 30 on a bolt 30, adjustably secured ina slot 31 in a latch 31, which latch is pivotally mounted on a stud 32on the downwardly extending arm 9 of the transferrer arm 9, in the usualway.

A helically coiled contraction spring 33 is attached at one 'end to anextension 24 on thehub 24 of the lever 24, and at its other end to a pin34 on the lay beam 1. The spring 33 acts to yieldingly move the lever 24toward the lever 26, and to hold the lever 26 in its locked position, asshown in Fig. 3. In this locked position the hunter 29 is .from thebobbin an held out of the path of the grooved end 30' on the bolt 30,see Fig. 3, and the loom is operated normally.

When the filling 6 on the bobbin 5 is practically or substantiallyexhausted, as shown in Fig. 4, the engagement of the projection 12 onthe feeler or detector 12 with the head 20 of the screw 20 on thelever'21, will move said lever 21, and also move the lever 24,sufficiently to disengage the end of the plate 25 on the'lever 26,withthe plate 24' on the lever 24, and allow the helically coiledcontraction spring 35, which is attached at one end to a pin 36 on thelay beam 1, and at its other end to the lever 26, to act to move thehunter 29 into the path of the grooved head 30 on the bolt 30 on thelatch 31 of the transferrer mechanism, so that on the forward movementof the lay, the t-ransferrer 9 will be operated to transfer a freshbobbin from the magazine 7 into the active shuttle.

The lever 26 carries in this instance a stud 26, on which is mounted aroll 26", on the lower side of the lever 26. The roll 26 is in positionto be engaged by the cam-shaped or inclined end 37 on an arm 37, secured.to or extending out from the loom side, not shown.

The engagement of the roll 26 with the camshaped or inclined end '37 ofthe arm 37 on the backward movement of the lay, will move the lever 26back to the position shown in Fig. 3, and cause the lever- 26 to belocked by the plate 24 on the lever 24, tohold the hunter 29, in itsinoperative position, as shown in Fig. 3. i

From the above description in connection with the drawings, theoperation of my improvements will be readily understood by those skilledin the art. As long as there is 5 in the active shuttle, the feeler orfilling detector, at every other pick of the loom, will engage thefilling on the forward movement of the lay, and be moved outwardly, asshown in Fi 3, and through intermedlate mechanism alcove described, thehunter 29 will be held in its inoperative position, as shown in Fig. 3and stationary relatively to the feeler. When the filling 6 on thebobbin 5 is practically or substantially exhausted, as shown in Fig.4,the filling-detector or feeler 12 will enter farther into the shuttle,and through the extension 12 thereon, cause the movement of the lever 21and the lever 24, to release the lever 26 and allow the spring 35 toactto move the hunter 29 into the path of the end 30 of the bolt 30 on thelatch 31, so

that on the next forward movement of the the transferrer mechanism willbe ut .and a fresh bobbin or filling lied to the shuttle to take theplace of the su stantially exhausted bobbin, on the same pick, thefilling feeler or detector 12 being positively moved away lay, intooperation,

carrier will be sup the shuttle, through its operating mechout of theopening in I,

end of the loom, and adapted to enter the.

shuttle to engage the filling, mechanism connected with said fillingdetector to move it into and out of engagement with the filling in theshuttle, a hunter, and connections intermediate said filling detectorand said hunter, tohold said hunter in an inoperative position andstationary relatively. to the filling detector, and said hunter releasedthrough the operation of said intermediate connections on the practicalexhaustion of filling, to put into operation the. transferrer mechanism.

2. In a weft'replenishing loom, a filling detector, pivotally mounted atthe magazine end of the loom, and adapted to enter the shuttle to engagethe filling, mechanism connected with said filling detector to move itinto and out of engagement with the filling in the shuttle, a hunter,and connections intermediate said filling detector and said hunter, tohold said hunter in an inoperative position and. stationary relativelytothe filling detector, and said hunter released through'the operationof said intermediate connections on the practical exhaustion of filling,to put into operation the transferrer mechanism, and means to move thehunter out of operative position.

'3. In a Weft replenishing loom, a filling detector pivotally mounted atthe'magazine end of the loom, and adapted to enter the shuttle to engagethe filling, mechanism connected with said filling detectorto move itinto and out of vengagement with the filling in the shuttle, saidmechanism having a yielding lever, a lever adapted to he engaged by thefilling detector on the practical exhaustion of the filling in theactive shuttle, adjusting means intermediate said last named lever andthefilling detector, and connections intermediate said last name leverand a hunter, and said hunter held in an inoperative position andstationary relatively tothe fillingdetector, and released on thepractical exhaustion of filling, and actuated by aspring, to he movedinto position to put into operation the transferrer mechanism.

4. In a weft replenishing loom, a filling detector pivotally mounted onthe lay at the magazine end of the loom, at the rear of the shuttle box,and adapted to be moved, through an opening in the shuttle box andshuttle, to engage the filling in the active shuttle, a. lever fast.onthe upper end ofa vertically extending rock shaft, and carrying anadjusting screw extending in the path of and adapted to he engaged by aprojection on the filling detector, on the practical exhaustion offilling in the active shuttle, a second lever on the lower end of saidvertically extending rock shaft, and extending in the path of andadapted to engage and hold a lever fast on a vertically extending shaft,and said shaft, having a hunter fast thereon, to be moved into the pathof and operate the transferrer'arm, on the substantial exhaustion offilling in the active shuttle, and meansfor moving said lever, 'to movethe hunter out of operative position.
